Conventional methods for the extraction of natural products from plant are characterised by the consumption of large volumes of solvent, energy, lengthy extraction procedures and the potentially deleterious degradation of labile compounds. In the last two decades there has been an increasing demand for new extraction techniques, amenable to automation, with shortened extraction times, reduced organic solvent consumption, prevention pollution in analytical laboratories and reducing sample preparation costs. Unmodified domestic microwave oven is used in the extraction of phenolicsfrom C. domestica Val. using water as solvent. The Microwave Assisted Extraction produced a better yield of crude extract of 48 mg compared to Soxhlet extraction methods with only an extraction yield 3.4 mg. Effects of extraction time, microwave power and solvent volume are evaluated on the extraction of phenolic compounds.References
